The 4099 V series high-temperature recirculating ovens are suitable for tempering, annealing, stress relieving, shrink fitting and heat treating large workloads. Designed for 1400F (760C) operation, the ovens are equipped with a high CFM stainless steel fan for recirculation. The fan assembly is roof-mounted, providing a vertical airflow pattern and uniform temperature throughout the chamber. A stainless steel liner forms the work area, and adjustable louvers balance the airflow and increase air velocity into the work chamber. The liner baffles the workload from the direct radiation of the heating elements.
